According to Swedenborg, plants in general represent facts, knowledge and ideas, so it makes sense that a forest in the Bible represents a collection or system of external, factual, scientific ideas. This can be a collection on its own, or it can be the collected external knowledge of a church. It can also represent the level of a person’s mind where he or she deals with such systems of ideas.
Passages from Swedenborg
Arcana Coelestia (Elliott) n. 9011
This is the case* with one who kills, who shall flee there so that he may live, when he has struck his companion unwittingly, when he did not hate him previously** – as when he goes with his companion into a forest to cut down timber, but when his hand with the axe in it is swung to cut down wood, the iron flies off the handle and hits his companion so that he dies,*** he shall flee to one of these cities so that he may live. Deut. 19:4, 5.
[3] This describes the state of one blameless and freed from punishment, who through the falsities of faith which he had believed to be truths, or through factual knowledge based on the illusions of the senses, has injured someone, and so has done harm to his internal or spiritual life. To convey this meaning such an accident or chance is described by an implement of some kind, and by a stone which he causes to fall onto his companion so that he dies, and also by the axe or iron coming off its handle, while both were cutting down timber in the forest. The reason why such details are used to describe the matter is that ‘an implement’ means some known fact, and ‘a stone’ a truth of faith or in the contrary sense a falsity; and in like manner ‘the iron of an axe’ and ‘cutting down timber’ means to argue about what is good, using what one’s religion teaches.
[4] Anyone may see that but for some hidden reason a killing that occurred accidentally would not have been described by the iron of an axe coming off its handle in a forest, for such an accident happens rarely, scarcely once in many years. But that accident has been described in such a way for the sake of the internal sense, which describes the harm done to a soul by another through the falsities of faith which, because his religion teaches them, he has believed to be truths. For anyone who causes harm through falsities which he believes to be truths does not do harm from set purpose or in spite of knowing better, because he acts in accord with his religious faith and therefore out of zeal. So that these things might be meant in the internal sense they are described, as has been stated, by those who kill companions accidentally, and by ‘a stone’, by ‘cutting down wood in a forest’, and by ‘the iron of the axe coming off its handle onto a companion during the process’. For ‘a stone’ is a truth of faith in the natural man, and in the contrary sense a falsity, see 643, 1298, 3720, 6426, 8609, 8941, and so is ‘iron’, 425, 426. ‘The iron of the axe coming away from its handle’ is truth separated from good, good being meant by ‘handle’ or ‘wood’, 643, 2812, 3720, 8354; ‘cutting down wood’ means placing merit in works, 1110, 4943, 8740; but ‘cutting down timber in a forest’ means discussing these and like matters, and also calling them into question; for ‘a forest’ means a religious system.
[5] Like matters are meant by ‘cutting down timber in a forest with axes’ in Jeremiah,
The mercenaries will go with strength, and they will come to her with axes, like those who cut down timber. They will cut down her forest, said Jehovah. Jer 46:22, 23.
Here ‘cutting down timber in a forest’ stands for acting in accord with false religious practices and destroying such things as constitute the Church. For the Church is called ‘a forest’, ‘a garden’, and ‘a paradise’; it is called ‘a forest’ by virtue of its knowledge, ‘a garden’ by virtue of its intelligence, and ‘a paradise’ by virtue of its wisdom, 3220, ‘trees’ being perceptions of goodness and truth, and also cognitions or knowledge of them, 103, 2163, 2722, 2972, 4552, 7690, 7692. And since ‘a forest’ means the Church in respect of its knowledge, thus of its external aspects, it also means religious practices.
[6] The Church in respect of its knowledge or external aspects is also meant by ‘aforest’, or ‘a wood’, in David,
The field will be exultant and everything in it; then all the trees of the wood will sing. Ps. 96:12.
In the same author,
Behold, we heard of Him in Ephrathah; we found Him in the fields of the wood. Ps. 132:6.
These words refer to the Lord. In Isaiah,
The light of Israel will be a fire, and his Holy (One a flame. It will burn the glory of his forest, and his Carmel; it will consume from the soul even to the flesh. As a consequence the remaining trees of the wood will be [so small] a number that a child may write them down. He will cut down the entangled boughs of the forestwith an axe,**** and Lebanon will fall by a majestic one. Isa. 10:17-20, 34.
‘The forest’ stands for the Church in respect of its cognitions of truth, and ‘Carmel’ for the Church in respect of its cognitions of good, in the same way as ‘Lebanon’ and ‘Hermon’ do. ‘The trees of the wood’ stands, as above, for cognitions, and ‘being a number that a child may write down’ stands for the fewness of them, ‘entangled boughs of the forest’ standing for factual knowledge, 2831.
[7] In the same prophet,
You said, By the multitude of my chariots I will go up [to] the height of the mountains, the sides of Lebanon, where I will cut down the tallness of its cedars, the choice of its fir trees, After that I will come to its remotest height,***** theforest of its Carmel. Isa. 37:24.
In Jeremiah,
I will visit on you according to the fruit of your works, and I will kindle a fire in its forest. Jer. 21:14.
In Ezekiel,
Prophesy against the forest of the field towards the south, and say to the forest of the south, Behold, I will kindle in you a fire, and it will devour every tree. Ezek. 20:46, 47.
In Micah,
Guide****** Your people with Your staff, the flock of Your inheritance inhabiting alone a forest in the midst of Carmel. Micah 7:14.
Does anyone fail to see that in these places a forest is not meant by ‘a forest’, nor Lebanon and Carmel, which were forests, by ‘Lebanon’ and ‘Carmel’, but that some aspect of the Church is meant? What aspect of the Church it is however has lain hidden up to now because the internal sense has lain hidden. But how astonishing that in a world so learned as Europe – more learned than all the other continents – where the Word exists, in every detail of which the internal sense is present, there is no awareness of that sense! Yet it was known to the ancients in Chaldea, Assyria, Egypt, and Arabia, and from them in Greece, in whose books, symbols, and hieroglyphics such matters are still met with. The reason why awareness of that matter has perished is lack of belief that what is spiritual has any real existence.
Apocalypse Explained 650
[26] In Ezekiel:
“Say unto the king of Egypt, and unto his multitude, Whom art thou like in thy stature? Behold Asshur, a cedar in Lebanon, fair in branch and a shadowy forest; his stature became higher than all the trees of the field, and his branches were multiplied because of many waters; all the birds of the heavens made their nests in his branches; and under his branches every wild beast of the field brought forth, and in his shade dwelt all great nations; he was fair in his greatness. But because thou art lifted up in stature,” he shall be cut down; “upon his ruin shall dwell every bird of the heavens, and upon his branches shall be every wild beast of the field” (xxxi. 2, 3, 5, 6, [7], 10, [12], 13).
The king of Egypt, and his multitude, signify the natural man with the scientifics therein; Asshur, the cedar in Lebanon, signifies the Rational, which is formed from scientifics on the one part, and from the influx of spiritual truth on the other. By fair in branch and a shadowy forest is signified intelligence through rational truths by means of scientifics; [27] by stature higher than all the trees of the field is signified elevation even to the interior Rational, which is from the Spiritual; by branches multiplied because of many waters is signified the abundance thereof by means of spiritual truths, which are from the knowledges of truth from the Word. The birds of the heavens, which built their nests in his branches, signify spiritual thoughts in rational things, for the Rational is the medium between the internal-spiritual and the external-natural man; the wild beast of the field which brought forth under his branches signify the affections for scientifics rationally perceived.
[49] That these things are signified by the bird of every wing and by the beast of the field, is evident from the passages hitherto explained, and also from this one in Isaiah:
“The saying of the Lord Jehovih, who gathereth the outcasts of Israel; yet will I gather these to his gathered ones; every wild beast of my fields, come ye to eat, every wild beast in the forest” (lvi. 8, 9).
The outcasts of Israel, whom the Lord will gather, signify all those in the church who are in truths from good and separated from those therein who are in falsities from evil. These are also meant by the wild beasts of the fields of the Lord Jehovih, for fields signify the church as to the implantation of the truth of doctrine; but the nations who are without the church are signified by the wild beast in the forest, the forest signifies the natural and sensual man, and the wild beast his knowledge (scientia), and thence obscure intelligence. That the wild beast of the field and the wild beast in the forest signify such things is evident, for it is said, “Come ye every wild beast of my fields, and every wild beast in the forest, to eat”; to eat signifies instruction and appropriation.
Arcana Coelestia 9642
[3] In Ezekiel,
Set your face the way of the south, and drop [your words] towards the south, and prophesy against the forest of the field to the south, and say to the forest of the south, Behold, I am kindling in you a fire, which will devour in you every green tree; and all faces from south to north will be scorched. Set your face towards Jerusalem, and drop [your words] against the sanctuaries, and prophesy against the land of Israel. Ezek. 20:46-21:2.
‘The south’ here stands for those who have the light of truth provided by the Word, thus those who belong to the Church, yet who are influenced by falsities which they substantiate from the sense of the letter of the Word wrongly explained. This is why the expressions ‘the forest of the field towards the south’ and ‘the forest of the south’ are used. ‘A forest’ is a state in which factual knowledge is predominant, whereas ‘a garden’ is one in which truth is predominant. From this it is evident what the meaning is of ‘setting one’s face the way of the south, and dropping [one’s words] towards the south, and prophesying against the forest of the field to the south’, and then of ‘set your face towards Jerusalem, and drop [your words] against the sanctuaries, and prophesy against the land of Israel’. ‘Jerusalem’ and ‘the land of Israel’ mean the Church, and ‘the sanctuaries’ there things of the Church.
[23] (II) A wilderness (desertum) also signifies the state of the church with the nations who were in ignorance of truth, and yet in good of life according to their religion, from which they desired truths, as is also evident from the passages in the Word, where the church to be established among the nations is treated of.
In Isaiah:
“The spirit shall be poured out upon you from on high, then the wilderness (desertum) shall be a fruitful field, and the fruitful field shall be counted for a forest; judgment shall dwell in the wilderness, and justice shall abide in the fruitful field” (xxxii. 15, 16).
This is said of those who are in natural good, and are being reformed. Influx out of heaven into such is signified by The spirit shall be poured out upon you from on high. That truth from a spiritual origin shall then be implanted in them, is signified by The wilderness shall be a fruitful field, – a wilderness denoting the natural man destitute of truths, and the fruitful field, or land of harvest, denoting the natural man made fruitful in truths; that as a result it will possess the knowledge (scientia) of the cognitions of truth and good, is signified by The fruitful field shall be counted for a forest; forest is said in reference to the natural man as a garden is to the spiritual, therefore a forest signifies knowledge (scientia), and a garden intelligence. That in it there will consequently be what is right and just is signified by Judgment shall dwell in the wilderness, and justice shall abide in the fruitful field; judgment and justice, in the spiritual sense, signify truth and good, but in the natural sense, what is right and just.
